Dumps of post-2015-manufactured carts fail MAC verification

[mariomadproductions]

E.g. Legend of Zelda, The - Majora's Mask 3D (Europe) (En,Fr,De,Es,It) passes verification, but Legend of Zelda, The - Tri Force Heroes (Europe) (En,Fr,De,Es,It) fails. The manufacturing date may not be that relevant, but it gives you an idea of which ROMs are affected at least. I checked a few pre-2015 carts and a few post-2015 carts.

Its possible this is a GodMode9 issue, and if so I'll close this issue and open on on its issue tracker, but I used GM9's verification function on one of the ROMs that fails in ctrtool, and it passed there, so I thought it made sense to open it here.

Thanks

Turns out I misunderstood how the initial-data key is selected. I checked TriForce heros, and while CTRTool currently fails the InitialData MAC, it would seem to be my mistake.

I'll comment here when I update CTRTool.

Can confirm the MAC verification fail. This might or might not help since it's a little easier to read than most other implementations:

@mariomadproductions
Please try these builds of CTRTool and let me know if that fixes the issue:
ctrtool-win_x64.zip
ctrtool-win_x86.zip
ctrtool-ubuntu_x86_64.zip
ctrtool-macos_x86_64.zip
ctrtool-macos_arm64.zip

That seems to have fixed it - I've tested it on a few that failed before and now they pass. Glad to see this wasn't a dumping error.

Thank you for testing this.

This is fix is included in the v1.0.4 release, which is available on the releases page.
